This experiment was conducted to study the spring productivity and feeding value of hairy vetch varieties. We also measured DM yield and feeding value by analyze CP and CF that authors made possible to calculate TDN and RFV. The results can be summarized as follows; Dry matter yield were increased earlier autumn seeding date and later cut in spring. Differences of dry matter yield in earlier cut in spring was high in order of Ostsaat, Welta, Vv4712, Penn-02, Common and Minnie. Crude protein(CP) yield was increased when earlier autumn seeding date and later cut in spring. Total digestible nutrient(TDN) yield of hairy vetch varieties was decreased when later autumn seeding date, and was increased when later cut in spring. TDN yield was highest in Ostsaat and Welta varieties had highest dry matter yield. Acid detergent fiber(ADF) content was decreased when later autumn seeding date and was increased when later cut in spring. Neutral detergent fiber (NDF) content was decreased when later autumn seeding date. Average values for relative feed value(RFV) were 157% and 132% in both cut. It shows that a high feed value in all of hairy vetch varieties. Above all, the results presented that the optimal seeding date for cultivating hairy vetch in the central region of Korea is between the 10th to the 20th of September. Because Ostsaat and Welta had significantly high dry matter yield we expected Ostsaat and Welta have a higher wintering ability.

본 연구는 경륜선수의 경기력에 영향을 미치는 심리요인을 수집하고 이들 심리요인의 구조를 탐색하고, 탐색한 요인의 적합성을 검증하는데 그 목적이 있다. 본 연구의 목적을 달성하기 위해 경륜선수를 대상으로 설문을 실시하여 자료를 수집하였다. 개방형설문 결과 경륜선수의 경기력에 영향을 미치는 426종류의 심리요인을 수집하여 내용분석을 실시하였다. 내용분석 결과를 바탕으로 243명의 경륜선수를 대상으로 설문을 시행해 탐색적 요인분석을 실시하였으며, 탐색적 요인분석 결과를 토대로 338명의 경륜선수를 대상으로 설문을 시행해 확인적 요인분석에 활용하였다. 연구결과 경륜선수의 경기력에 영향을 미치는 14종류의 심리요인이 채택되었으며, 채택된 심리요인은 경기전략, 경기력관리, 동기, 정신력 요인으로 구조화되었으며, 각각 경기전략 요인은 위기대처능력, 상황적응력, 순간판단력, 압박감 극복을 하위요인으로, 경기력관리 요인은 능력에 맞는 전법구사, 자기최면, 체력관리, 자기관리를 하위요인으로, 정신력 요인은 투지, 긴장감 해소, 승부욕을 하위요인으로, 동기 요인은 성취동기, 과감성, 긍정적 사고를 하위요인으로 구성하였다.

This study was carried out to investigate the effect of different mixture ratios of vermicasts on the growth of leaf beet(Beta vulgaris var. cicla), young radish (Raphanus sativus L), spinach(Spinacia oleracea) and lettuce(Lactuca sativa) The mixture of ratios of vermicast(fermented pig manure with sawdust) and peatmoss were 100%+0%, 60%+40%, 40%+60% and 0%+100%(control), respectively. The bulk density, particle density, pH, electrolytic conductivity, ash, total nitrogen, cation exchange capacity, available phosphorous and exchangeable cations increased significantly compared to those grown in the 100% of peatmoss(control). The significantly higher values of plant length, leaf area, shoot dry weight, root weight, root length and biological yield obtained were 40%~100% and 40% of vermicast in leaf beet and lettuce, respectively. The young radish and spinach showed that significantly differences of shoot dry weight, root weight and biological yield in the mixture ratios of vermicast were 40%~60% and 40% in young radish and spinach, respectively.

The purpose of the study is to identify a basic spatial unit for rural village redevelopment plan. An ideal spatial unit need to satisfy three basic premises: to be homogeneous as rural community, to be appropriate to implement the project, and to be compatible with regional planning systems. A spatial unit could, empirically, be defined based on the homogeneity at first, and then appropriateness and compatibility could be used to adjust its boundary. Mitan-Myun(13 villages), Pyungchang County, Dochuck-Myun(15 villages), Kwangju County, and Chuksan-Myun(28 villages), Kimje City in Korea were selected as case study areas. The degree of interrelationship between all possible pairs in each Myun was measured using spatial, socio-cultural, and economic indicators. Multidimensional Scaling(MDS) was used to identify a homogeneous spatial unit, and then indicators representing appropriateness and compatibility were used to adjust the identified boundary. New districts which have two or three villages were suggested as a reasonable spatial unit for rural village redevelopment, and its boundary roughly overlaps with Bup-Jeong-Ri(法定里: a legally defined village).
